[User] Crée un workflow n8n pour: Who is this for? This workflow is designed for professionals and teams who need to monitor multiple RSS feeds, filter the latest content, and distribute actionable updates as a Trello comment. Ideal for content managers, marketers, and team leads managing news or content pipelines. What problem is this workflow solving? Manually monitoring RSS feeds and keeping track of the latest content can be time-consuming. This workflow automates the aggregation, filtering, and distribution of news, ensuring that only relevant and timely updates are shared with your team or audience. What this workflow does: Aggregates RSS Feeds: Pulls data from up to three RSS feeds simultaneously. Filters Content: Filters articles based on their publication date (default: last 7 days). Organizes and Sorts: Sorts fil

**Analyse du besoin**

Cette tâche concerne un workflow d'automatisation pour la veille informationnelle via RSS. Le besoin identifié est triple : surveiller des flux RSS multiples, filtrer le contenu récent et distribuer les informations pertinentes sous forme de commentaires Trello. L'audience cible (content managers, marketeurs, team leads) indique un usage professionnel où la réactivité et l'organisation sont cruciales. Le problème résolu est l'élimination des tâches manuelles répétitives de surveillance et de diffusion d'informations.

**Choix techniques**

Pour ce type de workflow, n8n propose plusieurs approches techniques. L'utilisation de nodes RSS Feed pour l'agrégation, combinée à des nodes de filtrage temporel (probablement IF ou Filter), permet de sélectionner uniquement les contenus récents. L'intégration Trello nécessite le node Trello avec authentification API. Le trigger peut être basé sur un schedule (Cron) pour des vérifications périodiques, ou webhook pour une approche événementielle. La gestion de 12 nodes suggère une logique métier complexe incluant possiblement du traitement de données, de la transformation de contenu et de la gestion d'erreurs.

**Architecture**

L'architecture logique suit un pattern ETL (Extract, Transform, Load). L'extraction se fait via les nodes RSS Feed configurés sur différentes sources. La transformation inclut le filtrage temporel, le formatage du contenu et possiblement l'enrichissement des données (résumés, catégorisation). Le chargement final vers Trello nécessite une structuration spécifique des commentaires. La présence de 12 nodes indique probablement des branches parallèles pour traiter plusieurs flux RSS, des nodes de merge pour consolider les résultats, et des mécanismes de gestion d'erreurs pour assurer la robustesse du workflow.

**Points d'attention**

Plusieurs aspects critiques doivent être considérés. La fréquence d'exécution doit être optimisée pour éviter la surcharge des APIs RSS et Trello tout en maintenant la fraîcheur des informations. La gestion des doublons est essentielle pour éviter les notifications répétitives. L'authentification Trello doit être sécurisée avec une gestion appropriée des tokens. La surveillance des erreurs (flux RSS indisponibles, limites API) nécessite des fallbacks robustes. Enfin, la scalabilité doit être anticipée si le nombre de flux RSS ou d'utilisateurs augmente.

**Symptôme**: Le workflow s'exécute mais n'envoie aucun email
**Attendu**: Email envoyé avec les données
**Réel**: Aucun email reçu

[Assistant]
<thinking>
**Symptôme**: Le workflow ne produit pas le résultat attendu.

**Trace du flux**:
1. Vérification des données en entrée
2. Suivi de la transformation à chaque node
3. Comparaison avec l'output attendu

**Hypothèses**:
- Mauvaise expression d'accès aux données
- Node mal configuré
- Données manquantes en entrée
</thinking>

## 🔍 Diagnostic

**Problème identifié**: Le node précédent retourne un tableau vide car le filtre est trop restrictif

**Analyse du flux**:
1. Vérification des données à chaque étape
2. Le problème se situe dans le traitement des données

**Solutions**:

### Option 1: Corriger l'expression
Vérifier que le chemin d'accès aux données correspond à la structure réelle.

### Option 2: Ajouter du logging

**Analyse du besoin**

Cette tâche consiste à développer un système automatisé de génération de contenu blog pour produits Shopify. L'objectif est de créer un workflow n8n qui transforme des données produit brutes en articles de blog optimisés SEO, prêts à publier. Le système doit être capable de traiter automatiquement les informations produit, d'analyser les images pour extraire des données nutritionnelles, et de générer du contenu HTML structuré sans intervention manuelle.

Le besoin métier sous-jacent est clair : permettre aux e-commerçants de maintenir un blog actif pour améliorer leur référencement et engagement client, sans avoir à rédiger manuellement chaque article. Ceci est particulièrement pertinent pour les boutiques avec de nombreux produits où la création manuelle de contenu devient rapidement impraticable.

**Choix techniques**

L'utilisation de GPT-4o comme moteur de génération est judicieuse car ce modèle offre des capacités avancées de compréhension contextuelle et de génération de contenu de qualité. Sa capacité multimodale permet d'analyser directement les images produit pour en extraire des informations nutritionnelles, éliminant le besoin d'un service d'OCR séparé.

Google Sheets comme système de gestion des données présente plusieurs avantages : facilité d'utilisation pour les non-techniques, collaboration en temps réel, historique des modifications, et intégration native avec n8n. Cependant, il faudra considérer les limites de taux d'API Google si le volume devient important.

L'intégration Shopify via API REST permet une synchronisation bidirectionnelle fiable. La structure en 14 nœuds suggère une architecture modulaire avec des étapes distinctes pour chaque traitement, facilitant la maintenance et le débogage.

**Architecture**

Le workflow suit probablement cette logique séquentielle :
1. **Déclencheur** - Webhook ou schedule pour initier le processus
2. **Extraction Shopify** - Récupération des données produit via API
3. **Filtrage/Validation** - Vérification de la complétude des données
4. **Traitement des images** - Analyse GPT-4o pour extraction d'informations
5. **Enrichissement des données** - Compilation des métadonnées produit
6. **Génération du contenu** - Prompt engineering pour création d'article
7. **Structuration HTML** - Formatage du contenu généré
8. **Validation qualité** - Vérification de la cohérence du contenu
9. **Stockage Google Sheets** - Sauvegarde des données et contenus
10. **Publication** - Intégration avec le blog Shopify
11. **Gestion d'erreurs** - Traitement des cas d'échec
12. **Logging** - Traçabilité des opérations
13. **Notification** - Alertes de fin de traitement
14. **Nettoyage** - Maintenance des données temporaires

Cette architecture modulaire permet une évolutivité et une maintenance facilitées.

**Points d'attention**

**Gestion des coûts API** : GPT-4o étant un service premium, il faut implémenter des mécanismes de contrôle des coûts via limitation du nombre de tokens, mise en cache des résultats similaires, et optimisation des prompts pour éviter les générations redondantes.

**Qualité du contenu généré** : La mise en place de validation automatique de la cohérence, de la pertinence et de l'originalité du contenu est cruciale. Il faut prévoir des règles métier pour détecter les contenus génériques ou inappropriés.

**Gestion des erreurs et récupération** : Avec 14 nœuds et plusieurs services externes, la probabilité de pannes ponctuelles est élevée. Il faut implémenter une stratégie de retry intelligente, des mécanismes de fallback, et un système de queue pour

Sheets as a tracking system.\n\n## Step-by-step Workflow:\n\n### 1. Read Google Sheet\nBefore doing anything, call the Read Sheet tool to check if a blog has already been created for the Product ID. The sheet contains columns:\n\n- Timestamp\n- Product Id\n- Product name\n- Blog title\n- Blog url\n- Blog Html\n- Retry\n- Error\n\nCall this tool first and look up the row with the same Product Id.\n\n### 2. Check Conditions:\n- If the Product Id exists and Retry = No, skip this item.\n- If Retry = Yes, retry blog creation from Step 3.\n- If the Product Id is not found, proceed to Step 3 to generate and post a new blog.\n\n---\n\n### 3. Generate Blog Content\nBased on the following provided in the user message:\n- Product ID\n- Product Title\n- Product Description HTML\n- Product Nutrition Facts \n\nGenerate:\n- SEO-Friendly Blog Title\n- Meta Description\n- Formatted Blog Content in clean, structured HTML:\n  - Introduction summary\n  - H2/H3 subheadings\n  - Bullet points (key benefits, nutrients)\n  - Nutrient callouts or tables (if available)\n  - Closing paragraph or CTA\n  - Add internal keywords (tags)\n\n---\n\n### 4. Create Blog (HTTP Tool Call)\nCall the Shopify API to create a blog:\n\njson\n{\n  \"tool_call\": {\n    \"tool\": \"http\",\n    \"name\": \"Create Blog\",\n    \"method\": \"POST\",\n    \"url\": \"https://smartworkflow.myshopify.com/admin/api/2024-01/blogs.json\",\n    \"body\": {\n      \"blog\": {\n        \"title\": \"[SEO Blog Title]\"\n      }\n    }\n  }\n}\nOnce the blog.id is returned, post the article to:\n\n\nhttps://smartworkflow.myshopify.com/admin/api/2024-01/blogs/{{blog.id}}/articles.json\njson\nCopy\nEdit\n{\n  \"tool_call\": {\n    \"tool\": \"http\",\n    \"name\": \"Create Article\",\n    \"method\": \"POST\",\n    \"url\": \"https://smartworkflow.myshopify.com/admin/api/2024-01/blogs/{{blog.id}}/articles.json\",\n    \"body\": {\n      \"article\": {\n        \"title\": \"[Same Blog Title]\",\n        \"body_html\": \"[Generated HTML content]\",\n        \"tags\": \"nutrition, wellness, product, shopify\",\n        \"published\": false\n      }\n    }\n  }\n}\n6. Update Google Sheet\nIf Blog is Posted Successfully\nCall Update Sheet tool and set:\n\n\n{\n  \"Timestamp\":{{ $now }} ,\n  \"Product Id\": \"{{ $json.id }}\",\n  \"Product name\": \"{{ $json.title }}\",\n  \"Blog title\": \"[SEO Blog Title]\",\n  \"Blog url\": \"[Generated URL from blog.id and article.id]\",\n  \"Blog Html\": \"[Generated HTML]\",\n  \"Retry\": \"No\",\n  \"Error\": \"\"\n}\nIf Blog or Article Fails\nLog the error in Error column and set Retry = Yes.\n\n\n{\n  \"Product Id\": \"{{ $json.id }}\",\n  \"Retry\": \"Yes\",\n  \"Error\": \"[Detailed error message]\"\n}\n\nNotes:\nAlways call Read Sheet first before blog generation.\n\nRetry logic is based strictly on the Retry column.\n\nAll tool call responses should be handled using proper try-catch/error-check patterns.\n\nEnsure HTML is clean and includes correct spacing, paragraphs, H2s, bullet lists, and optionally nutrient tables.\n"},"promptType":"define"},"typeVersion":1.9}],"connections":{"If":{"main":[[{"node":"Main Product info","type":"main","index":0}],[{"node":"No Operation, do nothing","type":"main","index":0}]]},"OpenAI":{"main":[[{"node":"If","type":"main","index":0}]]},"Shopify":{"main":[[{"node":"Split Out","type":"main","index":0}]]},"Split Out":{"main":[[{"node":"OpenAI","type":"main","index":0}]]},"Read Sheet":{"ai_tool":[[{"node":"AI Blog Poster","type":"ai_tool","index":0}]]},"Update Sheet":{"ai_tool":[[{"node":"AI Blog Poster","type":"ai_tool","index":0}]]},"Simple Memory":{"ai_memory":[[{"node":"AI Blog Poster","type":"ai_memory","index":0}]]},"Create Blog id":{"ai_tool":[[{"node":"AI Blog Poster","type":"ai_tool","index":0}]]},"Create Articles":{"ai_tool":[[{"node":"AI Blog Poster","type":"ai_tool","index":0}]]},"Main Product info":{"main":[[{"node":"AI Blog Poster","type":"main","index":0}]]},"OpenAI Chat Model":{"ai_languageModel":[[{"node":"AI Blog Poster","type":"ai_languageModel","index":0}]]},"When clicking ‘Test workflow’":{"main":[[{"node":"Shopify","type":"main","index":0}]]}}}
